The Target Peripheral List (TPL) support is used to identify targeted
devices during Embedded Host (EH) compliance testing. Add TPL support
setting from device tree on ehci-platform, ohci-platform and dwc2 drivers.
Also document TPL support in DWC2 dt-bindings.
Changes in v2:
- Document TPL support in DWC2 dt-bindings
- Spell TPL and EH
- Add collected ack
Amelie Delaunay (3):
usb: host: ohci-platform: add TPL support
usb: host: ehci-platform: add TPL support
usb: dwc2: host: add TPL support
Fabrice Gasnier (1):
dt-bindings: usb: dwc2: document TPL support
